MAX4315 Maxim, MAX4315 Datasheet - Page 16

• Manufacturer Part Number: MAX4315
• Description: The MAX4310–MAX4315 single-supply mux-amps combine high-speed operation, low-glitch switching, and excellent video specifications
• Manufacturer: Maxim

High-Speed, Low-Power, Single-Supply
Multichannel, Video Multiplexer-Amplifiers
The multiplexer architecture of the MAX4310–MAX4315
ensures that no two input channels are ever connected
together. Channel selection is accomplished by apply-
ing a binary code to channel address inputs. The
address decoder selects input channels, as shown in
Table 2. All digital inputs are CMOS compatible.
Figures 10 and 11 show the evaluation board and pre-
sent a suggested layout for the circuits. This board was
developed using the techniques described in the
Layout and Power-Supply Bypassing section. The
smallest available surface-mount resistors were used

for feedback and back-termination to minimize their dis-
tance from the part, reducing the capacitance associat-
ed with longer lead lengths.
SMA connectors were used for best high-frequency
performance. Inputs and outputs do not match a 75Ω
line, but this does not affect performance since dis-
tances are extremely short. However, in applications
that require lead lengths greater than one-quarter of the
wavelength of the highest frequency of interest, use
constant-impedance traces. Fully assembled evaluation
boards are available for the MAX4313 in an SO pack-
age.
